Abstract: A sensor is disclosed which exchanges with associated data acquisition equipment a digital attribute signal, distinct from its transducer output signal, on the occurrence of a predetermined event. The invention is particularly illustrated with reference to an accelerometer which transmits sensor identification data to associated data acquisition equipment when power is first applied by using the same two signal lines as are used to provide power to the sensor and to convey the sensor output signal to the equipment. After the identification data is transmitted, the apparatus operates as a buffer amplifier to modulate the transducer output signal onto the same two signal lines.

Abstract: A fixing device (1) comprises a body (2) having a rear surface (4) from which extends a double key hole shaped boss (5). A pair of pins (7,8) project from the boss and receive therebetween a locking member (9) which is secured to the body member by a screw (10). In a first limit position (Figure 1) the locking member abuts the pins so that the fixing device may be offered up to a pair of panels having aligned double key hole shaped openings to pass the locking member (9) through the openings and leave the boss (5) positioned within the openings. The screw is then rotated from the side of the panel from which the fixing device was inserted to move the locking member (9) to a second limit position illustrated in Figure 3 defined when the leading faces of the locking member arms (12) abut the corners (13) of the pins (7,8). Continued rotation of the screw draws the locking member (9) towards the body member (2) to clamp the panels therebetween. The fixing device requires access only to one surface of the panels being clamped, and requires only appropriately shaped openings in the panels.

Abstract: A film leader of photographic film (5) can be advanced through a film passage mouth of a film cassette by rotating a spool of the film cassette (2) in the film unwinding direction. Upon the rotation, an indication changing mechanism moves an indicator plate into or from an indicator window (9) so as to change indication from unexposed to exposed. In a preferred embodiment, an advancing film (5) leader tears a seal attached on the film passage mouth when the spool is rotated. In another preferred embodiment, the film is provided with a magnetic layer, which supplies a camera with data as to the number of exposed frames in order to control a film transportation for preventing reuse of the film cassette. In still another preferred embodiment, the film cassette has labels instead of the indicator plate for indicating an exposed or unexposed state of the film cassette. In another preferred embodiment of the present invention, a switching mechanism is provided for connecting or disconnecting outer terminals through rotation of the spool. Since the switching mechanism switches the outer terminals only once irreversibly, the outer terminals keep the switched state. In a preferred embodiment of the photographic camera, contact members of the camera detect a connection between the outer terminals of the loaded film cassette. A detection signal is supplied for determining the exposed or unexposed state of the film.

Abstract: An oxide sidewall spacer is formed on the sidewalls of a gate prior to forming the body region of a DMOS transistor. An ion implantation or diffusion process is then conducted to form the body region, where the gate and the oxide sidewall spacer together act as a mask for self-­alignment of the body region. After a drive-in step to diffuse the impurities, the body region will extend only a relatively short distance under the gate due to its initial spacing from the edge of the gate. 
     After the body region is formed, the oxide sidewall spacer is removed, and impurities to form the source region are implanted or diffused into the body region and driven in. 
     Since the extension of the body region under the gate is limited by the oxide sidewall spacer, the channel region between the edge of the source region and the body region under the gate may be made shorter, resulting in the channel on-resistance of the transistor being reduced.
